IMPROVEMENT IN TEN'ONING--MAHINES- The Schedule referred to in theseLetters Patent and making part of the s'i'ame.

To all whom yit 'may concerny Be it known that I, WILLIAM Grnnonn, ofHudson City, in the'county of Hudson, and State ot' New Jersey, haveinvented a new and useful Improvement in Tenoning-Machine; and. I dohereby declare thatthe nying drawings, in which- Figure 1 represents aside view of my improved maf chine;

Figure 2, a front end of the same; and

Figure 3, a section of the sliding carriage and clamp, in the line :v :vof iig.- 1.

Similar letters of reference indicate corresponding parts.

A represents the framing of the machine. B, the table, on which thevertical carriagel C slide in ways arranged in a vertical position.

D is a vertically-reciprocating yoke, which carries the cutters E E,which are connected to the said yoke adjustably.

F is a treadle, .by which the cutter-gate or yoke is moved downwardagainst the action of the springs.

The springs raise'the cutter-gate, and keep it in an elevatedposition',- when the pressure of the foot is taken o the treadle F. l

a is a vertical rod, arranged to slide loosely in the brackets a Thelower end bears on the top of the cutter-gate, by which, and by theaction of grati-tation, it receives a reciprocating motion, which itcommunicates to the pawl-lever d through'the medium of the wiper b. l

The paWl-arm (l carries a pawl, d1, Working into the rack on the top ofthe carriageand feeds it towards the cutters.

d is a holding-pawl,- whichA prevents the Work from being drivenawayfrom the cutters by their action on it. v

c is a clamp, having a clamping-screw, c', by which the material, onwhich the -tenon is to be formed, is clamped to thel carriage, to be fedalong to the cutters.

wherebyit may be raised or lowered on the same, to hold material ofvarious sizes.

To operate-my improved n'lachin'e, a piece 'of tim ber is placed on thetable and screwed` up against the carriage by the clamping-screw, thevcarriage being drawn back far enough for the said piece of timber to befed up to the cutters the desired amount.

If the material be so thin as to' be too far towards the carriage toadmit ofthe teun being formed at of wood may be interposed between itandthe face of thc carriage.

It is then clamped tightly' by the screw.

Y The knives are then adjusted to the proper position on the gate, andalso to the proper distance apart, and the machine set in mot-ion by theapplication of the foot to the treadle F, by which the said timber isfed up to the cutters, and the tenon formed on both sides at the sametime, as will be fully understood without further description.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent, is-

The combination ofthe pawl-arm d, iv'ertically-slidin g rod a, and pawlsd d2, with the vert-ical carriage C, all arranged and operatingdescribed, for the purpose specified.

The above specification of my invention signed by me, this 18th day ofFebruary, 1868.
